Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of medical dredging devices, and particularly relates to a drainage tube blockage dredging device. Background Art
[0002] Drainage tubes are medical devices used for clinical surgical drainage, which guide pus, blood, and fluids accumulated between human tissues or in body cavities to the outside of the body to prevent postoperative infection and promote wound healing. Because purulent drainage and platelets in the blood will cause a coagulation reaction between the two, existing drainage tubes may become blocked, so that purulent or bloody drainage fluids at the wound will seep out from around the drainage tubes. On the one hand, the exudate can easily wet the dressing covering the wound, increasing the frequency of dressing changes by medical staff; on the other hand, the exudate can cause wound infection, increase the patient's recovery time, and increase patient expenses. Furthermore, drainage tubes are not suitable for frequent replacement, so when blockage occurs, the drainage tubes must be effectively unblocked.
[0003] Therefore, a drainage tube blockage dredging device is needed. Utility Model Content
[0004] The purpose of the utility model is to provide a drainage tube blockage dredging device, thereby solving the problem that the existing drainage tube is easily blocked by pus and blood coagulation during practical use. The specific technical solution is as follows:
[0005] A drainage pipe blockage unblocking device comprises a mounting shell, a semicircular heating cylinder, a torsion spring, a pressure plate, a rotating shaft, a protective shell, a wire, a pressure roller and a bracket, a semicircular groove is opened on the side wall of the mounting shell, two brackets are symmetrically mounted in the mounting shell, the line between the brackets is perpendicular to the line between the semicircular grooves, a rotating shaft is mounted on the brackets for common rotation, the pressure roller is fixedly mounted on the rotating shaft, the semicircular heating cylinder is mounted on the outer side wall of the mounting shell, the semicircular heating cylinder is coaxial with the semicircular groove and has the same radius, pressure plates are mounted on the outer side walls of the mounting shell and the semicircular heating cylinder, the pressure plates between the two groups of the mounting shells and the semicircular heating cylinders are rotationally connected by torsion springs, a protective shell is mounted on the outer side wall of the semicircular heating cylinder, the wire is connected to the semicircular heating cylinder and extends outside the protective shell.
[0006] Preferably, the bracket includes a movable plate, a fixed plate and a pressure spring, the fixed plate is installed in the mounting shell, the fixed plate is provided with a movable groove, the movable plate is slidably installed in the movable groove, the pressure spring is installed in the movable groove, the two ends of the pressure spring are elastically abutted against the movable plate and the inner bottom wall of the movable groove respectively, and the rotating shaft is rotatably installed on the movable plate.
[0007] Preferably, a speed limiting unit is also included, which includes a friction block and a tension spring. Both ends of the rotating shaft are provided with a plurality of movable holes in a circular array around the axis. The movable holes are located within the range of the bracket. The friction block is slidably installed in the movable hole. The tension spring is installed in the movable hole. Both ends of the tension spring are respectively connected to the friction block and the bottom of the movable hole.
[0008] Preferably, the outer side wall of the pressure roller is covered with a layer of anti-slip rubber pad.
[0009] Preferably, a plurality of balls for reducing friction between the drainage tube and the semicircular heating cylinder are installed in a circumferential array at one end of the semicircular heating cylinder away from the mounting shell.
[0010] Preferably, flanges are provided on both sides of the long sides of the semicircular heating cylinder, and a start switch is installed on the flange, and the start switch is electrically connected to the heater of the semicircular heating cylinder.
[0011] Preferably, the inner wall of the protective shell is covered with a heat-insulating material.
[0012] Compared with the existing technology, the utility model has the following beneficial effects:
[0013] 1. The utility model heats the blocked area of the drainage tube by forming a whole cylinder with two semicircular heating cylinders, so that the drainage tube expands due to heat, thereby reducing the adhesion between the blockage and the drainage tube. Then, the drainage tube is squeezed by two pressing rollers to push the installation shell to move the blockage until it is outside the drainage tube, thus completing the unblocking of the drainage tube. During the process of moving the installation shell, the semicircular heating cylinder will continue to heat the drainage tube on the path to ensure the smooth movement of the blockage.
[0014] 2. The utility model cooperates with the friction block and the tension spring. When the installation shell moves too fast, the centrifugal force will cause the friction block to move away from the rotating shaft, thereby contacting the moving plate to generate friction, thereby slowing down the movement speed of the installation shell, ensuring that the drainage tube on the path is heated evenly, and further ensuring the smoothness of the movement of the blockage in the drainage tube.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0024] Example
[0025] refer to Figure 1 and Figure 2A semicircular groove 9 is provided on the side wall of the mounting shell 1, and two brackets 8 are symmetrically glued and installed in the mounting shell 1. The connecting line between the brackets 8 is perpendicular to the connecting line between the semicircular grooves 9. A rotating shaft 4 is installed on the bracket 8 for common rotation through a bearing, and a pressure roller 6 is fixedly installed on the rotating shaft 4 through a key connection. The semicircular heating cylinder 2 is installed on the outer wall of the mounting shell 1 through a buckle. The semicircular heating cylinder 2 is coaxial with the semicircular groove 9 and has the same radius. A pressing plate 3 is installed on the outer wall of the mounting shell 1 and the semicircular heating cylinder 2. The pressing plates 3 between the two groups of mounting shells 1 and the semicircular heating cylinder 2 are rotatably connected through a torsion spring. A protective shell 5 is installed on the outer wall of the semicircular heating cylinder 2 through a buckle, and the wire 7 is connected to the semicircular heating cylinder 2 and extends outside the protective shell 5. Generally, the torsion spring will combine the two semicircular heating cylinders 2 into a cylinder. When the user presses the pressing plate 3 to squeeze the torsion spring, the two semicircular heating cylinders 2 rotate and open. At this time, the semicircular heating sleeve can be aligned with the blocked position on the drainage tube, and then the drainage tube blockage dredging device can be fixed on it, and fixed by the friction between the two pressure rollers 6 and the drainage tube. The interior of the semicircular heating cylinder 2 is a resistance wire that can be heated quickly. The wire 7 is used to connect to the power supply. After the two pressure rollers 6 squeeze the drainage tube, they push the mounting shell 1 to drive the blockage to move until it is outside the drainage tube, completing the dredging of the drainage tube. During the movement of the mounting shell 1, the semicircular heating cylinder 2 will continue to heat the drainage tube on the path to ensure the smooth movement of the blockage.
[0026] refer to Figure 3 and Figure 4 The bracket 8 includes a movable plate 801, a fixed plate 802 and a pressure spring 803. The fixed plate 802 is installed in the installation shell 1 by gluing. The fixed plate 802 is provided with a movable groove 10. The movable plate 801 is slidably installed in the movable groove 10. The pressure spring 803 is installed in the movable groove 10. The two ends of the pressure spring 803 are elastically supported by the movable plate 801 and the inner bottom wall of the movable groove 10 respectively. The rotating shaft 4 is rotatably installed on the movable plate 801. The bracket 8 is an automatic telescopic adjustment structure. When encountering a drainage tube with a thicker wall, the movable plate 801 will squeeze the pressure spring 803; when encountering a drainage tube with a thinner wall, the pressure spring 803 will push the movable plate 801 to drive the pressure roller 6 to move in a direction close to each other. The pressure spring 803 can automatically adjust the wheelbase between the two rotating shafts 4 while ensuring that the two pressure rollers 6 have sufficient drainage pressure, ensuring that the semicircular heating cylinder 2 can always be combined into a whole cylinder, thereby improving the practicality of the drainage tube blockage dredging device.
[0027] The outer wall of the pressure roller 6 is covered with a layer of non-slip rubber pad to prevent the pressure roller 6 from having relative friction with the drainage tube during the forward process, causing damage to the drainage tube, and also to prevent the speed limiting unit from failing. A plurality of balls 14 are installed in a circumferential array at one end of the semicircular heating cylinder 2 away from the mounting shell 1. Since the drainage tube is generally soft and curved, the balls 14 can prevent the right angles at the end of the semicircular heating cylinder 2 from having more friction with the drainage tube, causing damage to the drainage tube. Flanges are provided on both sides of the long side of the semicircular heating cylinder 2, and a start switch 15 is installed on the flange. The start switch 15 is electrically connected to the heater of the semicircular heating cylinder 2. When the two semicircular heating cylinders 2 are combined into a whole cylinder, the start switch 15 will be triggered, thereby starting the resistance wire for heating. When the user presses the pressing plate 3 to open the two semicircular heating cylinders 2, the start switch 15 stops being triggered and the resistance wire stops starting. The start switch 15 can prevent the user from accidentally touching the semicircular heating cylinder 2 when moving and disassembling the drainage tube blockage dredging device, resulting in the user being scalded.
[0028] refer to Figure 5 , multiple movable holes 13 are formed in a circular array around the axis at both ends of the rotating shaft 4, and the movable holes 13 are located within the range of the movable plate 801. The friction block 11 is slidably installed in the movable hole 13, and the tension spring 12 is installed in the movable hole 13. The two ends of the tension spring 12 are respectively connected to the friction block 11 and the bottom of the movable hole 13. When the installation shell 1 moves too fast, the centrifugal force will cause the friction block 11 to move away from the rotating shaft 4, thereby contacting with the movable plate 801 to generate friction, thereby slowing down the movement speed of the installation shell 1, ensuring that the drainage tube on the path is evenly heated, and further ensuring the smooth movement of the blockage in the drainage tube.
[0029] In summary, the utility model can conveniently and quickly discharge the obstruction in the drainage tube out of the drainage tube by heating and squeezing the drainage tube, thereby achieving unblocking of the drainage tube.
